An insulation device for a low-temperature pipe according to the present disclosure includes: a pair of primary insulation materials surrounding a first radially outer surface and a second radially outer surface of the pipe; a pair of secondary insulation materials surrounding outer surfaces of the primary insulation materials; a pair of tertiary insulation materials surrounding outer surfaces of the secondary insulation materials; a pair of finishing covers surrounding outer surfaces of the tertiary insulation materials; an out-profile coupled to each of the finishing covers so as to surround each of widthwise opposite ends of the finishing cover; and an in-profile coupled to each of the finishing covers so as to surround each of lengthwise opposite ends of the finishing cover, wherein the pair of secondary insulation materials are configured such that each of opposed contact surfaces thereof is formed in a shape bent at least one time.

A cellular glass system for an outer surface of a pipe or vessel. The insulation system has an outer surface and an inner surface and comprised of segments of cellular glass. A sealant is provided at the interface between the individual cellular glass segments and is configured to limit water intrusion and prevent corrosion.

A refrigeration cycle device includes a heat source, a first use unit, a second use unit, a first connection flow path, and a second connection flow path. The heat source has a compressor and a heat-source side heat exchanger. The first use unit is separated from the heat source unit and has a first use-side heat exchanger. The second use unit is separated from the heat source unit and has a second use-side heat exchanger. The first connection flow path connects the heat source unit to the first and the second use units and causes a first refrigerant to flow. The second connection flow path connects the heat source unit to the first and the second use units and causes a second refrigerant to flow. A specific enthalpy of the second refrigerant is smaller than a specific enthalpy of the first refrigerant.

A reinforced insulation jacket for a pipe includes a first jacket member and a second jacket member, each jacket member including a dimensionally stable, thermally insulating material having the shape of a semi hollow cylinder. Both the first jacket member and second jacket member have substantially identical cross sectional shape and are adapted to be joined to form a hollow cylinder, thereby enclosing the pipe to be insulated. A reinforcement member is located within the dimensionally stable, thermally insulating material body of at least one of the jacket members. This reinforcement member generally comprises a rod component and two end cap pieces. The end cap pieces generally are plastic, and rod component, in various embodiments, generally includes iron, steel, or a hard plastic, and generally is a rigid rod. The reinforcement member provides additional stiffness to the dimensionally stable, thermally insulating material body of the jacket member.

A pipe coupling for coupling a first pipe to a second pipe wherein a gap exists between a first pipe end and a second pipe end. The pipe coupling includes a tubular insert configured to fit within the gap and match an inside diameter and outside diameter of the pipes, thereby providing a through-butt joint between the insert and the pipes. The pipe coupling also includes a half-tubular first fitting section and a half-tubular second fitting section, configured to snap-lock and form a tubular shape over the insert, the first pipe end and the second pipe end. In some embodiments, the insert is integral with the fitting sections.

The invention relates to a channel element for a ventilation system. The channel element has a first opening (O1), a second opening (O2), and a channel wall which extends between the openings and surrounds a channel section. The channel element has a tubular section (25) and a thermally insulating envelope section (20) which is paired with the tubular section and envelopes same at least in sub-regions. The invention further relates to a channel element system made of individual channel elements which are connected together in series and a building envelope which contains such a channel element system.

A method for assembling a reinforced non-compressible pipe support by inserting a plurality of generally cylindrical holes in a first sheet of insulation in a pre-determined pattern, inserting a similar group of holes in at least a second sheet of insulation so that the holes of both sheets line up when the first sheet is placed against a pre-determined cylindrical or flat form and the second sheet is placed on top of the first sheet thereby forming contiguous voids where mating holes are positioned adjacent each other, applying a pressurized flowable material to fill each void along its longitudinal axis, and curing the material until it forms a hardened material thereby forming the plurality of sheets into a non-compressible arcuate body having an inner radius of curvature that fits against a pipe or into a rectilinear block. Multiples sheets may be adhered and thermoplastic or resin used to fuse them together.

A pipe anchor is disclosed having a pipe trunnion stop for attaching to an outer surface of a pipe by welding. A mating top cradle and a bottom cradle generally encircle and hold a length of the pipe. The bottom cradle has a pass-through to accommodate the pipe trunnion stop. There is a base onto which the bottom cradle sets, the base includes a void into which the pipe trunnion stop is secured. An insulation layer is positioned between the pipe and the top cradle and bottom cradle, and around the pipe trunnion stop. A bolting assembly on the top cradle and a mating bolting assembly on the bottom cradle secure the top cradle and the bottom cradle to each other. Another embodiment includes multiple pipe trunnion stops along with respective pass-through and base void sections.
